I'd like to add you to my professional [wireless] network

This is talk was given at Nodebots NYC, covering my journey into hardware networking and why I ended up landing on Tessel. For clickable links, I have a public [PDF](https://dl.dropboxusercontent.com/u/74986127/Nodebots-Professional-Wireless-Network.pdf) and [HTML](https://dl.dropboxusercontent.com/u/74986127/Nodebots-Professional-Wireless-Network/index.html) available as well.

18. A REFERENCE ARCHITECTURE FOR THE INTERNET OF THINGS
19. Port Forwarding
20. Does everything really need to be connected to "The Cloud"?
21. Can we make our own "Cloud" or Internet?
22. How to Network • Internet Protocol version 6 (IPv6) • Packets • Dynamic Host Configuration Protocol (DHCP) • Wi-Fi
23. Internet Protocol version 6 (IPv6) • Every device on the Internet is assigned an IP address for identification & location definition • Proposed in 1998 by Internet Engineering Task Force (IETF) • Successor to IPv4 • Uses 128-bit address (instead of 32)
24. Packets • the basic unit of transport for digital communications networks • A sequence of bytes (1's and 0's) that contain a source address, destination address, and body • headers === metadata, i.e. sender/receiver address • body === the information the sender wants the receiver to have, must be less than 64KB
25. Packets IPv6 packet header
26. Dynamic Host Configuration Protocol (DHCP) • Protocol for dynamically assigning IP addresses • Used to control the network configuration of a host through a remote server • Consists of various message types, i.e. DHCPDISCOVER, DHCPOFFER, DHCPREQUEST • the IP address assigned by server to client is on a lease
27. Wi-Fi / WiFi • Any "wireless local area network" (WLAN) product based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards • Less secure than wired connections • First version of the 802.11 protocol was released in 1997 • Suggested method of security is WPA2
28. Can we make our own "Cloud" or Internet?
